Hello, Chloe Remodeling.
This option is currently not offered since there are states that still prohibit this type of transaction. For now, you can refer to the workaround provided by my colleague above.
Also, bank transfers are free and swiping or using QuickBooks card reader is cheaper than online invoice payment. You might want to offer these payment methods to your customers.
Always feel free to drop by again if you have other questions with QuickBooks.
